Handling procedures
- Initial handling guidelines
Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.
1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.- Subculture guidelines
- All seeding densities should be based on cell counts gained by established methods.
- A guide seeding density of 2x104 cells/cm2 is recommended.
- Cells should be passaged when they have achieved 80-90% confluence.
- Culture medium
- McCoY5a + 10% FBS
- Cryopreservation medium
- Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.

Supplementary info

- Activity summary
Dystrophia myotonica protein kinase also known as DMPK is a serine-threonine kinase with a molecular mass of approximately 69 kDa. The protein localizes mainly in muscle heart and brain tissues serving critical roles in cellular signaling. DMPK influences various cellular processes through its kinase activity modulating several substrates by phosphorylation. This protein is generally expressed in the cytoplasm but can also localize to membranes influencing ion channel activity and cytoskeletal dynamics.
- Biological function summary
DMPK acts to regulate muscle function and integrity by modulating phosphorylation states within cells. It is not typically part of known multi-protein complexes but works alongside other kinases to affect signaling pathways. For example DMPK can influence actin filaments and myosin phosphorylation contributing to muscle cell contractility and stability. This regulatory function is essential for the maintenance of normal muscle tone and function.
- Pathways
DMPK participates actively in RhoA and MAPK signaling pathways. DMPK impacts the RhoA pathway by regulating cytoskeletal organization and cell morphology interacting with proteins like Rho kinase to modulate muscle contraction. In the MAPK pathway DMPK plays a role in stress response signaling impacting proteins such as ERK that control gene expression in response to stressors.
- Associated diseases and disorders
DMPK is strongly connected to myotonic dystrophy type 1 (DM1) a genetic disorder characterized by muscle weakness and myotonia. Aberrant expression of DMPK due to triplet repeat expansions in its gene leads to toxic RNA accumulation disrupting normal cellular function. This disorder also shares pathogenic features with MBNL1 where both proteins influence RNA-binding and processing contributing to the DM1 phenotype. Understanding the role of DMPK in these conditions may offer insights into potential therapeutic strategies.
